Difference between LP and HP
Hey, I have an E-99 and just decided to get a little more serious about pb and upgrade it and stuff. When I was researching HPA tanks to get I read the forums and someone said that if the tank is low pressure then you need a regulator but if its high pressure you just put the tank on and your ready to go.
is this right? if so, how can you tell between hp and lp (3000psi / 4500psi ?) and what are the differences.
thank you for your time.
